Definitions

  • a variety of systems and devices have been made and used for treating morbid obesity.
  • Some such systems and devices include adjustable gastric band systems, which are operable to restrict the flow of food from the esophagus into the stomach.
  • Some gastric bands include a fluid-filled elastomeric bladder with fixed endpoints that encircles the stomach just inferior to the gastro-esophageal junction. When fluid is added to the bladder, the band expands against the stomach, creating a food intake restriction or stoma in the stomach. To decrease this restriction, fluid is removed from the bladder.
  • Examples of gastric bands are disclosed in U.S. Pat. No. 7,416,528, entitled “Latching Device for Gastric Band,” issued August 26, 2008, the disclosure of which is incorporated by reference herein.
  • Another example of such an adjustable gastric band is disclosed in U.S. Pat. No. 6,067,991, entitled “Mechanical Food Intake Restriction Device,” issued May 30, 2000, the disclosure of which is incorporated by reference herein.
  • an adjustable gastric band system includes an injection port configured to receive the needle of a syringe assembly to add or withdraw fluid to or from the gastric band
  • an injection port configured to receive the needle of a syringe assembly to add or withdraw fluid to or from the gastric band
  • U.S. Pub. No. 2006/0211914 entitled "System and Method for Determining Implanted Device Positioning and Obtaining Pressure Data" published September 21, 2006, the disclosure of which is incorporated by reference herein.
  • Such parameter data may be obtained before, during, and/or after adjustment of a gastric band, and may be useful for adjustment, diagnostic, monitoring, or other purposes, and may also be obtained with respect to a mechanically actuated gastric band.
  • pressure data may be used to determine whether the amount of fluid in the gastric band needs to be adjusted; and/or for other purposes.
  • gastric bands may be difficult to use as a result of slipping post-installation.
  • the user may install a gastric band at a particular location, only to have the gastric band later slip or roll to an undesirable location.
  • Such inadvertent movement of the gastric band may cause undesirable results and/or suboptimal treatment with the gastric band.

  • Gastric band (20) of the present example comprises an inflatable bladder (22) that is secured to a flexible strap (24).
  • Inflatable bladder (22) may be formed of silicone or any other suitable material or combination of materials.
  • Catheter (18) provides fluid communication between bladder (22) and the reservoir of injection port (12).
  • catheter (18), bladder (22), and injection port (12) form a closed fluid circuit.
  • a needle that is inserted through septum (16) may be used to add or withdraw fluid from inflatable bladder (22), to adjust the restriction created by gastric band (20) as described in greater detail below.
  • gastric band (20) is configured and operable in accordance with the teachings of U.S. Pat. No. 7,416,528, entitled "Latching Device for Gastric Band," issued August 26, 2008, the disclosure of which is incorporated by reference herein.
  • gastric band (20) may have any other suitable configuration and/or operability.
  • gastric band (20) is applied about the gastro-esophageal junction of a patient.
  • gastric band (20) is installed such that bladder (22) is adjacent to the tissue of the gastro-esophageal junction, with strap (24) on the outside of bladder (22).
  • the ends of strap (24) are secured relative to each other when gastric band (20) is sufficiently wrapped about the patient's stomach (2).
  • strap (24) is flexible in this example, strap (24) substantially resists stretching along its length. Accordingly, when fluid is added to bladder (22) (e.g., using a needle inserted through septum (16) of injection port (12), etc.), bladder (22) expands and exerts inward forces on the gastro-esophageal junction of the patient.
  • an installed gastric band (20) at least substantially encloses the upper portion of stomach (2) near the junction with esophagus (4) in the present example.
  • FIG. 3 shows gastric band (20) in a deflated configuration, where bladder (22) contains little to no fluid, thereby maximizing the size of the stoma opening into stomach (2).
  • FIG. 4 shows gastric band (20) in an inflated, fluid-filled configuration, where bladder (22) contains substantially more fluid than is shown in FIG. 3. In this configuration shown in FIG. 4, the pressure of gastric band (20) against stomach (2) is increased due to the fluid within bladder (22), thereby decreasing the stoma opening to create a food intake restriction.
  • FIG. 4 also schematically illustrates the dilation of esophagus (4) above gastric band (20) to form an upper pouch (6) beneath the diaphragm muscle (8) of the patient.
  • gastric band may be desired for use with gastric band system (10).
  • gastric band (20) such as one depicted in FIGS. 1-4
  • gastric band (20) may be prone to undesirable slipping, rolling, or otherwise failing to maintain a desired location on the esophagus or stomach.

  • Gastric band (220) further comprises a fluid port (236).
  • Outer band (230) is sized to fit around the outside of inner band (234). Both outer band (230) and inner band (234) are sized to wrap around a portion of esophagus (204). Alternatively, outer band (230) and inner band (234) may fit around a stomach rather than a portion of esophagus (204). Outer band (230) comprises a generally flexibly rigid biocompatible material, but any suitable material may be used as would be apparent to one of ordinary skill in the art in view of the teachings herein. Inner band (234) comprises an inflatable portion such that inflating inner band (234) forms a gastric restriction. A plurality of tabs (232) are connected to outer band (230).
  • Tabs (232) may be integrally formed into outer band (230), may be attached after outer band (230) is constructed, or may be of unitary construction with outer band (230). Tabs (232) have a rounded, wing-like shape extending outwards from outer band (230). However, tabs (232) may have any shape as would be apparent to one of ordinary skill in the art in view of the teachings herein. In the illustrated version, tabs (232) are symmetrically positioned on opposite sides of outer band (230). In relation to each other, pairs of tabs (232) are distributed equally along the length of outer band (230). In some alternative versions, tabs (232) may be positioned in different arrangements along outer band (230).
  • Tabs (232) are further shaped so as to slope gently towards the ends of tabs (232). Furthermore, tabs (232) may be rigidly flexible. That is, tabs (232) may be flexible enough such that through use, no inadvertent damage is caused to the stomach; yet rigid enough to provide stability to gastric band (220). Tabs (232) may further comprise a variety of textures such as a ribbed or bumped outer surface. However, any suitable texture for tabs (232) may be used. It will be appreciated that tabs (232) may aid in stabilizing gastric band (220). Tabs (232) may also comprise other features, some examples of which will be discussed in more detail below.

Abstract

L'invention porte sur un appareil qui permet de former une restriction gastrique et qui comprend un anneau implantable et au moins une languette. Dans certaines versions, la ou les languettes peuvent servir à stabiliser l'appareil lorsqu'il forme une restriction gastrique. Dans certaines modes de réalisation, une ouverture peut être formée dans les languettes de sorte que des sutures puissent être utilisées. Dans encore certaines versions, un échafaudage et/ou une matrice de tissu peut être utilisée sur l'anneau implantable et/ou les languettes afin de faciliter un support à long terme pour l'anneau implantable, par exemple en empêchant l'anneau implantable de coulisser sensiblement le long d'un axe défini par une structure anatomique autour de laquelle l'anneau implantable est enroulé.
